MPC8321ZQADDC

Overview

The MPC8321ZQADDC is a PowerQUICC II Pro integrated communications processor featuring an e300c2 core operating at 266 MHz. It includes a QUICC Engine with five Unified Communication Controllers (UCCs), a Security Engine (SEC 2.2), and a 32-bit DDR1/DDR2 memory controller supporting up to 266 MHz. The device provides a 32-bit PCI interface, four DMA channels, USB 2.0, and various serial interfaces including Ethernet, TDM, HDLC, UART, SPI, and I2C.

Feature Summary

• Integrates a single RISC QUICC Engine block for programmable protocol termination and network interface support.
• Includes a dedicated security engine providing hardware acceleration for cryptographic algorithms such as DES, AES, and SHA-1.
• Features dual integer units within the e300c2 core to enable efficient parallel execution of operations.

Applications

• ADSL SOHO and residential gateways
• Modem/routers
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type, temperature range, and encryption status. Confirm current lifecycle status and availability through authorized distributors, as this component may be subject to obsolescence or supply constraints.

Selection Notes

Select this processor for designs requiring a balance of CPU performance and networking flexibility. Ensure the system design accommodates the required power sequencing for core and I/O voltages. Verify software compatibility with existing PowerQUICC-based designs if migration is planned.

Part Context

This component belongs to the MPC8323E family of cost-effective, highly integrated communications processors. It extends previous PowerQUICC offerings by adding higher CPU performance and faster interfaces while addressing time-to-market and power consumption requirements for networking applications.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers within the MPC8323E family or other PowerQUICC series components that match the required pinout and feature set.
